I'm developing a project using Symfony for the final project of my Bachelor and I have to write reports about the design and the architecture of my project. While there's definitely a part of the design that is defined by me there's a lot of details that are imposed by Symfony and that are difficult to unserstand directly from the use of the framework itself while following the documentation.

So what I'd like to ask is if anyone knows of some diagrams (class diagrams, sequence diagrams, components diagrams, etc...) that illustrate the inner workings of symfony so that I can include them on my report (with the proper credit of course).
